===================================================================
Google doesn't allow using Chrome's API keys in Chromium builds and
strongly recommends against doing so. These OAuth 2 credentials are
taken from publicly available sources, but their fitness for use in
Chromium builds is not warrantied.
===================================================================

!!! Use these keys to reactivate Sync in Chromium at your own risk;
    they are extremely likely to stop working in the (near) future.

$ grep oauth2 ~/.config/chromium-flags.conf
--oauth2-client-id=77185425430.apps.googleusercontent.com
--oauth2-client-secret=OTJgUOQcT7lO7GsGZq2G4IlT

Note: The above works on Arch Linux because of its custom launcher,
      plus a patch to reuse --oauth2-client-{id,secret} for setting
      GOOGLE_DEFAULT_CLIENT_{ID,SECRET} similar to environment vars.
      
https://wiki.archlinux.org/index.php/Chromium#Making_flags_persistent

Or also, the credentials can be placed on ~/.profile
In this case, there is no need for chomium launcher's replacement.

If you are going to use personal keys, I think you will have to subscribe to the google-browser-signin-testaccounts mailing list in order for sign-in to work. See this post for more information.

Sorry would it be possible to provide a bit more explanation on how to use this approach. If I enter this grep says unrecognized option

The command is just grep oauth2 ~/.config/chromium-flags.conf showing that the following two lines should appear in ~/.config/chromium-flags.conf (after you add them of course). The alternative is passing the values with environment variables (GOOGLE_API_KEY can only be passed as an environment variable, there is no flag), or building them into the binary if you compile from source.

Thanks, sorry yes I should have been able to figure that out. Created the file and added the lines. It works great!

Unrelated, but is there a good way to make the opening of docx etc. work. For me it works on Chrome, but not chromium

Hello all,

thank you very much for this discussion. However, it looks like I am still missing something.
I created API keys and all credentials according to the guide on

https://www.chromium.org/developers/how-tos/api-keys

And then launched chromium with these environment variables to re-enable the APIs (log back into Sync, etc.) with:

export GOOGLE_API_KEY=...
export GOOGLE_DEFAULT_CLIENT_ID=...
export GOOGLE_DEFAULT_CLIENT_SECRET=...
chromium

Unfortunately, I am still unable to log in to my Google account from within Chromium-Dev (92.0.4484.7). After entering my Google username, I only get the message "This browser or app may not be secure. Try using a different browser."

What do I have to do in addition in order to enable my newly created credentials in Chromium-Dev?

OK, looks like the browser's user agent has to be changed to something more convenient to Google (example: Chrome on Windows):
Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36

Hello All,

I'm doing the setup on a mac, and global imports don't work on mac as they should on a normal unix system, so I thought I could prevent some headaches:

/etc/default or ~/.profile variable imports are not passed to applications ran with spotlight or aqua/finder, so you should pass the variables to launchd to be able to inherit variables within applications ran with aqua/finder/spotlight.

You have multiple ways of setting global variables using launchd:

1. Setting environment variables using a launchd unit : see the link

2. You can add global variables to launchd within your shell's .profile or /etc/default with adding the following lines:

GOOGLE_API_KEY=""
GOOGLE_DEFAULT_CLIENT_ID="client_id_you_saw_under_oauth"
GOOGLE_DEFAULT_CLIENT_SECRET="client_secret_you_saw_under_oauth"

launchctl setenv GOOGLE_API_KEY $GOOGLE_API_KEY
launchctl setenv GOOGLE_DEFAULT_CLIENT_ID $GOOGLE_DEFAULT_CLIENT_ID
launchctl setenv GOOGLE_DEFAULT_CLIENT_SECRET $GOOGLE_DEFAULT_CLIENT_SECRET

Add these into the LSEnvironment section in Chromium.app/Contents/Info.plist before launching for the first time:

	<key>LSEnvironment</key>
	<dict>
		<key>MallocNanoZone</key>
		<string>0</string>
		<key>GOOGLE_DEFAULT_CLIENT_ID</key>
		<string>...</string>
		<key>GOOGLE_DEFAULT_CLIENT_SECRET</key>
		<string>...</string>
		<key>GOOGLE_API_KEY</key>
		<string></string>
	</dict>
